No USB connection - phone not seen!

[---]

I lost USB ssh access after a recent update (including kernel as I remember) into my UBPorts edition. Can't see the phone by lsusb, ip a, or dmesg. The situation is the same independent of OS (including postmarketOS without UI), either running from eMMC or SD card. Inspecting the initramfs via the debug-shell would not work. PostmarketOS troubleshoot suggests adjusting kernel configuration parameters referencing: CONFIG_USB_ETH CONFIG_USB_ETH_RNDIS CONFIG_USB_G_ANDROID.  Anybody know the appropriate parameters I should be looking for?

[---]

Well, still cant figure this one out. nmcli reports usb0: unmanaged "usb0" ethernet (musb-hdrc), --:--:--:--:--:--, hw, mtu 1500.
I don't know if the usb circuitry is dead, results appear the same without the usb-c cable connection.
Can anybody see anything in these dmesg excerpts?

looks like usb0 was renamed enp0s26u1u5.

Dev name changes happened for more stability in device names.

You could try changing usb0 part in network setup (computer end) to the name enp0s26u1u5.

Please ask for help in our Matrix chat rather than here on the forum, you are much more likely to get proper help.

@RTP -  I've been trying to rename usb0 on the phone without success. The value appears to be referenced by GENERAL.DEVICE. Might udev be involved?

@PureTryOut - thanks for the suggestion - will do.

Part of "Predictable Interface Names" changes. For more 'stable' device names.

I was seeing similar style issues when trying to flash multiple OSes to emmc or sdcards using the device. Try a different cord first. I found that the cord that was supplied quickly deteriorated.  This was causing the devname to change constantly on the device. No clue why.  Could watch it using `udevadm monitor`

udevadm monitor unresponsive to the phone diss/connecting. Bizarrely, just after reading your suggestion nmcli showed the phone and I was able to usb/ethernet access it for a moment (first time since July). Rebooted and lost it again - guess I'll get another cable. Thanks @plainenough.

[NobodyNew1]

I had the same issue, phone wasn't showing up. The fix for me, was to not have any other USB devices plugged in aka my mouse dongle. Once that was unplugged the phone showed up.
